How do you find the area of a circle with pi? You always have to measure the diameter or the distance on how long it is. From there you get the measurement and then you multiply it by pi and you get your answer. For example say you have a circle of about 3.25 inches in its diameter. You had to measure that in order to get the inches and then you have to multiply it by pi in order to get the answer of 10.21. Of course, I rounded, but before we multiply we are going to have to round pi to 3.14 or you'll just get the longest of the numbers.
Here is another example: If you have a circle of about 13 inches what would be the answer? Well all we would have to do is multiply 13 by 3.14, and we would get our answer of 40.82 inches in the circle's area. That is a simple easy way to find the area of a circle.
